Tracked on [LRS-656]

• Some UI enhancements and alignments
• Unit test

Hi Realsense team, contributor here (docs mainly!) but was looking through release notes and saw this issue and story.

What is the reference to [LRS-656] and is that an internal tracker? Would love to learn more about this feature and what it is. Does this feature mean that if you adjust auto exposure settings, currently it only affects RGB and not the IR Stereo depth? Happy to read more somewhere else.

Also noticed quick typo in the Matlab source, I can open a PR for it, I don't use it, but saw this misspelling of exposure:

Would you like a PR for this quick fix and some docs on this?

Hi @seebq ,
Thanks for your interest.

Yes, we keep track in an internal system

Would love to learn more about this feature and what it is

The accelerated AE is only for the depth stream and only relevant for D455 at the moment,
this is an improved algorithm that is faster than the previous one and should output a more accurate result.
On this PR I also did some cosmetics and renamed the color AE to really state color so users (and developers) can distinguish between them.

About the type, nice catch! feel free to open a PR for that, sounds like a valid fix :)

We are excited to try this. We have a couple hundred D455s in the wild using outdoor stereo depth, and interested in what the accelerated auto exposure will do.

Specifically hope to improve this issue at this timestamp in my video of a limitation with our D455 stereo depth algorithm:

We've tried a few things with autoexposure regions, and we have an IR filter on these cameras....
