No, there are no differences between 3.7 and 3.7.1 in this respect.
There are many reasons why a legacy scene may /still/ look washed-out:
- The scene might be using explicit `ambient` settings.
- Even though partial blame is now put on `ambient`, it is also still
true that pigment colours specified using `rgb` will /per se/ tend to
look less saturated and brighter in an `assumed_gamma 1.0` scene than in
a legacy scene.
- As demonstrated, non-linear gamma messes up /any/ combination of
multiple finish effects (e.g. diffuse and reflection) in a very
non-linear fashion; consequently, any scene tweaked to look reasonably
good despite these quirks /will/ most certainly look unexpected when
setting `assumed_gamma 1.0`, and will essentially have to be "un-tweaked".
- Another potential factor is that you may simply have gotten accustomed
to the excessive contrast of non-linear scenes over the years, and may
now be expecting more contrast than is realistic. (Reality is rarely
"moody" -- even professional photographers routinely "cheat" on such
scenes, from employing tinted spotlights to choosing a highly non-linear
photographic film to applying tonemapping in a post-processing step.)
