A few thoughts about this tool-
In my mind, this is not a display mode, it’s not a render style, it’s not a filter pack…
it’s an art supply…Like paint or chalk or pencils.
flair will affect a scene differently in reaction to lighting, materials, reflections, transparency, flair type etc… for instance, you can ray trace an image for a few samples, then stop it, leaving a ton of noise in it, then apply flair to that image and get wild painterly like effects.
Like an art supply it’s got a lot of things that you can explore… also like an art supply it can be a bit tough to replicate a “look” from one model to the next.

Notice the different stuff you can do with it, and feel free to experiment beyond just applying a flair at it’s defaults… mess with lights, materials (shiny stuff looks different than matte etc) , focal blur, backgrounds, textures, and display mode (pencil on a wireframe gives a cool effect) etc
biggest issue atm is it’s windows only…
