DCI-P3
Also known as: P3, Display P3, wide color, P3 color space
DCI-P3 is a wide color gamut originally defined for digital cinema and now common on phones, tablets, and laptops. It covers noticeably more saturated greens and reds than sRGB, so P3 content looks more vivid on a display that supports it.

Wider than sRGB
DCI-P3 reproduces a larger range of colors than sRGB, the older consumer standard, especially in deep reds and greens. Apple's Display P3 variant adapts it for screens, and many recent iPhones, iPads, and Macs both capture and display in this wider gamut.
On a P3 screen, P3 photos and video show richer, more lifelike color. On a screen limited to sRGB, those extra colors are squeezed back into the smaller range, so the vividness is lost.
Why it is tagged
Files carry a color-space tag so software knows to interpret their values as P3 rather than sRGB. Without the tag, wide-gamut colors can look oversaturated or wrong on devices that assume sRGB.
Choosing P3 over sRGB does not meaningfully change file size on its own; storage is driven by resolution, bit depth, and compression, not the gamut label.
