What I said was accurate, whole wheat contains tryptophan but not wheat gluten. Tryptophan is only contained in the part of the wheat berry that gets removed when you make vital wheat gluten. The amino acid breakdown for wheat gluten isn't part of the USDA database but someone did do a study on it:

TVP as a standalone product usually isn't fortified but food manufactures use TVP to create mock meats and the end product is often fortified, for example:

On the contrary, soy protein is dramatically higher quality than gluten. What you posted isn't a measure of protein quality, its referring to crude values. Also the values aren't correct either, the values for "seitan" appear to be for whole wheat. You need to look at the Protein Digestibility Corrected Amino Acid score. Wheat gluten has a score of just 25 where as soy has a score of 91 which is on par with meat. Note also that whole wheat has a higher score than gluten, that is because some amino acids (like tryptophan) get removed when gluten is isolated.

Also note as the name implies, they are already adjusting for digestibility.
You're ignoring the point as a standalone food wheat gluten tastes terrible where as the same isn't true for lentils, vegetables, etc. They are palatable without adding a ton of salt or infusing them with large amounts of fat.
