not multiple bulbs no, but those bulbs have multiple LEDs in them… LEDs only have a single colour, but you can produce variable colour (or colour temperature) bulbs by mixing R/G/B or warm white and cold white

philips hue bulbs for example have red, green, blue, warm white, and cold white LEDs so they can mix any colour or colour temperature

to have variable colour temperature requires a warm white and a cold white LED that get mixed, so they’re always being used at 50% or less (because 50% emission on both is the same brightness as 100% of 1)… commercial fixtures are likely to not give that option and only include a single LED at fixed colour temperature to avoid 2x the parts
