TMT environment variables can't be used in plan environment variable subustitution

[BeeGrech]

Variables listed https://tmt.readthedocs.io/en/stable/overview.html#variables are not passed in a substituted form, they are only literately substituted when the test is executed

For example in my plan:

environment:
    INTERNAL_INCLUDE_PATH: $TMT_TREE/storage/include/bash_modules/lxt

in my test file I intended to use this for an import statement for directory structure.
runtest.sh:

INCLUDE_PATH=${INTERNAL_INCLUDE_PATH:-/some/dir/modules/lxt}

where the result is

line 16: $TMT_TREE/storage/include/bash_modules/lxt/utils.sh: No such file or directory

but it would be nice to be able to pass this through the plan variable also. Because if I were to have declared a line in the test with the $TMT_TREE var this works

That is indeed the current behavior. I'm not saying it's the desired behavior or the right or wrong behavior, just the current one, you're not missing any secret handshake. Values are treated as literals, and exported into the plan and test environment as-is.
