There is no technical reason for this, just a manufacturing choice.

I don't think it's quite that simple. There are significant technical considerations given the small packaging of consumer bulb designs (primarily heat dissipation and broad spread of the light - LED sources are nearly point sources of light). Not to mention the costs of the various colors, manufacturing and packaging that are required to get to a more 'normal' wide distribution in color such as incandescent gives off. So there are big technical impacts due to cost constraints as well for us 'cheap' focused consumers.

A stage light show has few constraints on packaging size nor on initial cost of purchase relative to general consumer products.

It's not "simple" but LED technology is very well understood and is dirt-cheap to manufacture when you scale it up. The whole point of using LED technology is that it generates a whole lot of light for the amount of power (heat) consumed). The expense in the light bulb is the power supply, not the microelectronics. ...and yeah, I do this stuff for a living.
