Azure pipeline yaml: Cannot use strategy matrix variable in conditions - azure

Question

I am having problem in calling template as the pre-condition is not getting satisfied, I am comparing parameter value to select which template to call at runtime, here I am having parameter value coming from strategy matrix and I think that might be the issue.
pipeline yaml :
stages:
- stage: build_stage
jobs:
- job:
strategy:
matrix:
Dev_Build:
build_type: "dev"
Rel_Build:
build_type: "rel"
steps:
- template: test_conditional_template.yml#templates_repo
parameters:
build: $(build_type)
test_conditional_template.yml :
parameters:
- name: build
type: string
default: 'dev'
steps:
- ${{ if eq(parameters.build, 'dev') }}: # this condition is not working
- template: test_conditional_template_generic.yml#templates_repo
parameters:
build_quality: ${{ parameters.build }}
test_conditional_template-generic.yml :
parameters:
- name: build
type: string
default: 'dev'
steps:
- script: |
echo "build quality : ${{ parameters.build }}"
displayName: "print build quality, test_conditional_template-generic"
I am not even able to compare the parameter value with normal script step too :
- script: |
echo "build quality : ${{ parameters.build }}"
condition: eq('${{ parameters.build }}', 'dev')
This is what pipeline prints for above step :
if template is called with hard-coded parameter value, condition works fine :
steps:
- template: test_conditional_template.yml#templates_repo
parameters:
build: 'dev' #this works fine with above template code
we're avoiding so much of boilerplate code with usage of strategy matrix so dont really want to get away from it, any pointers will be helpful.

I wanted to add this as a comment but my first thought was that it's comparing 'dev' with "dev" in the first example and ''dev'' (double single quotes) in the script example, so both would evaluate as false,
I've been writing quite a few templates and have had a lot of similar issues, it would be nice if we could find out before checking the code in but ehh yaml...
