You are asking the wrong question in a few threads. Start with
What is CCT? When you see why the CCT of a filament is lower than that of sunlight, and can guess what the CCT of a red-hot machine part must be, you are able to ask the right question: Spectral Distribution depends on what parameters? How does this affect CRI, CCT, and Tint?
Most white LEDs are built on a blue diode. This emits blue light in a narrow distribution.
A phosphor is deposited atop this. It absorbs blue photons and emits photons in a range of colors - Red, orange, yellow, green. Deep purple will not be present, so extremely purple flowers may look strange. Deep purple pigments are rare otherwise.
This phosphor is covered in a protective material to protect it from oxidation. If this material were flat, some light would be re-reflected into the phosphor, increasing heat retention, decreasing output, and changing the color distribution. Restriking photons can down-convert again to a redder color. To reduce restrike and internal reflection, this protective covering is domed.
So changing the Dome, the Phosphor, the Die will change the Spectral power distribution. This is the whole symphony we describe with the terms CRI, CCT, and Tint.
