Not just leds, back long ago shading was an issue with only MH too, plus back then most the sps you got were colonies by today’s standards which magnified the issues.
When you have nice clean sand or glass there imo is enough reflection on smaller colonies to prevent issues, but with large colonies shading is an issue but with every light source if they get large enough - same with flow. We just don’t have many people that have that large of colonies.
