`UIVisualEffectView` with blur alters hue and makes image darker or lighter - how to fix?

Question

I would like UIVisualEffectView to just give me gaussian blur without any lightening or darkening. But UIBlurEffect.Style only has styles that alter the image in some way.

How can I achieve that without using CIImageFilter, vImageBoxConvolve_ARGB8888 and raw CoreGraphics whatsoever, just purely with UIVisualEffectView?

Answer 1

There is no way to achieve this using CoreAnimation.
