IIUC the conclusion is that there is no need for a string attribute
because we only need to distinguish between 'perceptual' and
'non-perceptual'. If that is correct, do you have any preference for
the attribute name ('perceptual_scale', 'perceptual', ...)?

More a summary than a conclusion! There is a reason I have left a bit or
space for others to comment on this over the last month (and a bit).

To be clear my Reviewed-by: means that I believe that the kernel is better
with "non-linear/linear/unknown" than without it and that I am comfortable
the API isn't likely to be a millstone for us.

No, not really.  Happy to leave it to your good judgement.
