No, I just assume that the the phosphors react sufficiently linear with 
respect to electron beam intensity vs. emitted light intensity, as well 
as interaction with scattered light. If that is given (and as of now I 
have not heard of anything to the contrary), it does not matter how much 
the beam widens at high intensities, or how much optical scattering 
occurs in the phosphors: Both effects then just change the distribution 
of the light emission, but preserves the overall brightness.

If you doubt this presumption, you can still try with a coarser pattern 
and a diffusor like a sheet of paper.


Also note that if there was a nonlinear effect of color bleeding on the 
overall brightness acting in favor of the 3.7 gamma, then the same 
effect would have been present in the checkerboard pattern as well, 
partially countering the black/white transition nonlinearities in there 
that favored the 3.6 settings.
