Color shift when exporting JPEG

Good day! I have a question I make Instagram posts with still images from the project. In the color tab, capture a standard frame and then in the gallery expotriruyu in JPEG with the application of LUT monitor. And I have a shift of colors and scales. How do I fix this? When exporting the project to H264 QT or mp4, everything is fine. But when exporting JPEG or TIFF, there is a shift in gamma and color? Can this be fixed?

My simple method: always export a second or two of SMPTE color bars at the very head of the project, and then check them on scopes in whatever player you're using to see how it looks. If there's a shift (video level or hue or chroma), you'll see it very quickly in bars.
