Cinema prints were not made warmer because xenon lamps are cold
Question asked:
“Cinema prints were intentionally made warmer because the xenon lamp used to project them was very cold.”
Summary
Cinema film prints were not designed to be warmer; xenon projection lamps generate a great amount of heat and often require cooling systems. The lamps are hot, not cold, so there was no need to compensate by making the prints warmer.

HPM lamps are also limited to outputs of 100s of watts and are used in multiples of two for added reliability. Xenon lamps for cinema were first introduced by Osram in 1951 and have become highly reliable, allowing the use of one lamp per projector. The lifetime of larger lamps can range from 800 to 1200 hours.

A xenon arc lamp is a highly specialized type of gas discharge lamp, an electric light that produces light by passing electricity through ionized xenon gas at high pressure. It produces a bright white light to simulate sunlight, with applications in movie projectors in theaters, in searchlights, ...

When running 35mm, the projector should be equipped with a water-cooled gate for lamps exceeding 3kW. Regulating heat is even more important when running 16mm, because the light is focused on a smaller surface area. Film can also be damaged by a lamp that is misaligned, creating a hotspot that blisters (see "embossing" below) one portion of the frame. A 1.2kW Ushio xenon lamp in its shield.

The testing I've done previously shows no change in color temperature due to amperage changes. I suspect there is a color temp change over the life of the lamp, particularly if the quartz envelope darkens, but I don't claim to have any good data on that · Don't forget that SMPTE 196M allows ...
