We have about 20 different rendering modes for debugging content.  For
dealing with texture and uv mapping issues, in addition to the mode you
describe, we have two others.

One mode renders each mesh with a debug texture painted to indicate the
largest texture used by its material.

The other is very similar to the mode you describe except it applies a mip
map bias relative to the difference in size between the largest texture used
by the original material and the "mip map debug" texture.  Instead of
showing the size of the mip map actually being used by the hardware, this
mode displays the mip level selected for each material.  White indicates our
top mip level and we tell the artists that every mesh should turn white at
its closest normal viewing distance.
