OK, then assume they are not so well defined. BUT. As I look at the
filtered images I see no difference as to how well is the shape defined
in original and in filtered images. It's just that some details are
washed out, but the shape remains defined to same extent (which you
think is not enough).

I can only say I have to disagree. I see there more degrees of freedom
when defining 3D (meaning isometric perspective) shape than in defining
2D (meaning head on perspective) shape, which basically means that we
are able to further distinguish in 3D between shapes that are
indistinguishable in 2D. And I think one should be able to clearly
distinguish *between* the shapes.

Sadly, I don't know this game.

That I don't see them it does not mean that I don't care about them. I
appreciate what you did, but I fail to see the problem there - my eyes
or brain just are not capable of seeing the problem where you see it (so
your guidance in this matter would be appreciated). You are the one with
experience, so if You could help to improve the guidelines, it would
make Echo better in the future.
And once more to the shape... My eyes aren't so good when seeing distant
objects, so I tried to go further from my PC while looking at tritanope
image. All shapes there lost their clear differences between themselves
more or less at the same time, so when I say I do not see there a
problem it means that I do not see it physically, from which one could
assume that the problem isn't here, but you say it is here, so I am most
