Cadmium based coating/glazing in coloured bulbs

Since acquiring the 10x Mazda red coloured GLS bulbs that have a very vibrant appearance when lit up makes me think, does the red coating of these specific ones contain cadmium? When switched off the coating is not too vibrant - like a 'cardinal red' sort of appearance

From what I know is that cadmium based coloured incandescent bulbs have a very vibrant appearance when unlit, But could it be the case with ones that are like my Mazda red GLS bulbs I got recently?

Also when did cadmium stopped being used in coloured GLS bulbs?
