Enjoying the post, thanks for putting it up. Since banding & srgb was mentioned, does a larger sensor like medium format help with this? Also, I seen a u-tube vid with a Scottish landscape photographer Alex Neil was on as a guest & says he does his whole color workflow from capture to print in srgb, I know a little off the OP's subject but ,,,
The main take away from medium format is the bigger field of view and larger pixels, in number and physical size.
To some degree they do help capture smoother gradients/colors but sensor design, analog to digital converter & the bit depth are the real players when it concerns banding. An inappropriate monitor may also show banding even when the file does not have it.
With regards to TIFF, it is a container file type. It can contain a representation of the full RAW file plus "tags" or instructions and other stuffs bundled with the image. In a way, it is not dissimilar to PDF or a Word document, only it was designed primarily for image handling, like DNG etc. with the aim of standardizing print files.
Meaning, it is just a matter of choice to use it or not in one's work flow.
I for one, prefers PNG instead of TIFF for high gamut images if not printing them directly. Otherwise, I use Illustrator as my container, instead of TIFF.
RGB or Adobe RGB is a colorspace that has a bigger gamut than sRGB. The issue is that most printers are only capable of showing the gamut of sRGB. Hence, it is possible to get off-colors during the conversion in the printer from RGB to sRGB.
If one is intent on printing at the end, then choosing and working on the smaller sRGB colorspace may be a better option for a more consistent and predictable result.
The main thing to remember in handling image files is that it can only degrade. Meaning one can start from the highest quality and in every conversion or editing step, it becomes worse, even if the file size becomes bigger.
Hence, Non-destructive editing like ACR should be the first step and if possible should only be the step carried and the first conversion to PNG or JPG etc, be the last step.
