preserving RGB color quality from heatmap figures during exporting

I wish to export in RGB heatmaps that were created using imagesc and pcolor for output. The MATLAB .fig outputs look beautiful using the "jet" color map. However, regardless of the format type (.svg, .eps, .png, etc.) the colors get blunted with the blues becoming more purplish and reds and oranges shifted more to the yellow spectrum. This still occurs despite setting/using the export feature in the figure menu to output in RGB. Ultimately, I wish to import the colormaps into adobe illustrator for figure making purposes. Only when I switch to CMYK in Adobe do the colors somewhat return to how it appeared in the original MATLAB figure, but the hues are much less vibrant and dulled. I didn't have this issue previously until recently updating MATLAB and cannot find any information how to bypass this issue. I'm using MATLAB 2020b and using a Mac.
How can I preserve in any graphical export type the same RGB color quality from the original heatmap figure?
Thank you for any help or suggestions.
%Code generating figure:
T = imagesc(pts, pts, conv2(N, g, 'same'));
figure, pcolor(T.CData);
shading(gca,'interp');
colormap(jet(4096));

Can you post a screenshot of the image side by side in MATLAB and Adobe Illustrator?
