You are starting with what is most likely a wrong interpretation, seeing this is a greyscale photo, so we don't have any colour information, and if we don't have that you cannot say that the "dome" is silver/maybe metal.

To give everyone a little more detail on this dome anomaly, and its surroundings, I went to Google Mars to see if I could make some measurements. Using the coordinates of 35N 15E, I found the site fairly quickly. Yes, you can see this area, and you can see the anomaly feature, but only if you know what you are looking for already. This makes for a good comparison for just how bad the Google Mars photo data can be, as compared to the "near actual" NASA photos in the OP.
But the Google data here is good enough to use the Google Mars calculator to make the measurementsI wanted. And here they are:
The dome measures about 350 ft tall, and 400 ft in diameter. ie, more than a football field wide, and more than a football field tall, One just doesn't get that size perspective, looking at a pic of the dome in the screenshot.
The crater just below the dome measures about 2,500 ft in diameter
The smaller underground entrance, just below the dome, measures about 900 feet wide and 500ft tall
The larger underground entrance, forward of the dome, measures about 2,200 ft wide and 500 ft tall. That would be about 7 football fields wide. and nearly 2 football fields tall. That is a pretty large opening!
For most of us, when looking at these photos, it is difficult to really know how big, or how small, the Martian surface features are. Sometimes, we can go to Google Mars, and make the measurements we need, and that is a good thing. But often, the Google info is not good enough for that either.
I hope these measurements give everyone a better feel of size relative to the dome anomaly, and the nearby features..

Here is a 200% blowup taken from the JPEG2000 image (full image format). The resolution is 5.91 m/pixel, making the "dome" about 130 meters across. I see no circular shape. I see no circular windows. I see no underground entrances.
Oh. Don't use Google Mars for research.
Hi Phage! I always enjoy seeing your very serious avatar! Now Phage, you know full well when a photo is over magnified/pixelated. You pic is, and that is just one of the reasons you can't see the circular black spots on the face of the dome. If you go back to the screenshot in the OP, you should be able to see them easy enough. But, you don't have to do that, because I am going to repost it in a following reply, for you, and for other reasons.
The openings, which "might" be underground entrances, are clearly visible in the pic you posted. Looking at the OP screenshot, one of the openings that could be an underground entrance, is just below the dome feature. The larger opening is forward of the dome, and just aft of the crater at the front/bottom of the pic. I don't know how you can't see those either?? But i do accept that you don't!!
You and I are pretty close together on estimating the width of the "dome". You say you "don"t see a circular shape" Well, I say, I don't see any "edges or corners on it, and the roof is curved downward, as if it were a dome". Looks like a dome to me!! Of course, our dome anomaly could be just the "Bridge" of an alien ETV!
Phage, I agree relative to not using Google Mars for final photo data and posting. I've been there and done that! Everyone has to learn. But, as I have said in other posts on ATS, Google Mars can be useful to use for research, and for just looking around, because Google Mars also has on the spot links to the "Spacecraft Imagery", with the NASA MOC pics being clickable, right there. And too, the Google Mars measurement tool is useful, at times.
Thanks a lot for your comments!!!
