Edgy Bloom Effect with URP
Post processing bloom looks very strange. it looks normal if I remove the Lightweight RP or if I turn the bloom down. Is there a fix for this? Thanks
btw, this is a screenshot not a phone image

This issue is usually referred to as color banding. It exists because computers use integers to represent (compress) floating-point numbers. Here it's 32bit color space so 4 integers of 0-255 (byte) value range each per pixel color.
When it happens in textures - you need to adjust their color range, compression settings, maybe reduce color palette etc.
When it happens because of shaders or post processesing - you may want to enable HDR or try working around it by tweaking their code and settings until it's no longer as apparent.
Thank you very much. I had to enable HDR in the renderer settings. that worked!
