Maybe the empire have stereoscopic monitors instead of holograms?

Is that the same idea from the beginning of TPM, with the queen on the wall?

i say just a thought to improve visual and de retroize the noise look (it has been mentioned before) is to take the exposure/light concept that we see in ROTS

It is an idea, but I would prefer to leave it the same. It would take some of the emotion away from ROTS. Also, adding it would shift the focus away from what is supposed to be going on in the scene. Eye candy can't interfere with important plot advancing scenes.
