Not sure how you would get list of width/height and associated pixel format for that width/height.

For cameras, the pixel format can vary with width and height and can be yuv, rgb, mpeg, etc. Not all width/height values support all 
pixel formats and you may get duplicates of width/height with different pixel formats.

I create a list of width/height values and normally choose the best compression for a particular width/height. Compressed formats 
can make a lot of difference CPU wise coming over USB.

Anyway, this may be accounted for somewhere and just not seeing it.
