The only time you might see a difference would be if there were colors in the LAB spectrum that are not in the RGB spectrum, and those differences would rarely be noticable in a photograph.

A good point - but nospam's contention is conversion differences.

Let's color the situation. The files were taken from raw, reduced in=20 size, saved as TIFF in each RGB and Lab. Re-loaded and compared=20 (differenced). There is not a hint of delta.
