They are identical OETF based on a gamma curve and used for SDR-TV. [3] [2] [4] BT.1886: The ITU-R Recommendation BT.1886 is the reference EOTF of Standard Dynamic Range TV (SDR). [5] sRGB: sRGB defines a transfer function based on a gamma curve and used for monitors, printers and the Web. sRGB is standardized as IEC 61966-2-1:1999 [6]
The sRGB standard defines the chromaticities of the red, green, and blue primaries, the colors where one of the three channels is nonzero and the other two are zero.The gamut of chromaticities that can be represented in sRGB is the color triangle defined by these primaries, which are set such that the range of colors inside the triangle is well within the range of colors visible to a human ...
sRGB was created after the early development of Rec.709. The creators of sRGB chose to use the same primaries and white point as Rec.709, but changed the tone response curve (sometimes referred to as gamma) to better suit the intended use in offices and brighter conditions than television viewing in a dark living room.

The dynamic range that can be perceived by the human eye in a single image is around 14 stops. [10] SDR video with a conventional gamma curve and a bit depth of 8-bits per sample has a dynamic range of about 6 stops, assuming a luminance quantisation threshold of 5% is used. [10]
Since sRGB is the standard colorspace for webpages and computer screens, this gives only an idea of the intended colors. They are not completely representative of how they look on TV displays, since these follow the ITU-R BT.1886 standard, specifying a different gamma correction value, and thus colors below will look darker on such a display ...

A study confirmed that side effects like pancreatitis and kidney damage are possible while taking GLP-1s like Ozempic. Here's what a doctor wants you to know.
BT.1886 EOTF is as follows: [1] = ([(+),]) where is the screen luminance, in cd/m 2.; is the input video signal level, in the range [,].; is the exponent of the power function and equal to 2.4
