Template within template?

Emulated Hue and Sleep Cycle app on a template switch to trigger morning routines as well as turning off the light when setting the app.
But I have an input_select that allows me to select the bedside light I’m using. (have toddler, so I regularly have to sleep in guest room).

But the value_template doesn’t reflect my actual light status, which is changed by input_select.

Current value_template:

{{ is_state('light.master_bedroom_1', 'on'}}

Input_select that allows me to select which light I’ll be using:

{{states.input_select.w_bed_light.state}}

This returns pre-populated entity ID, such as “light.bedroom_2_light_bulb”. I then use this in my morning routine script and turn_off command action the selected light.

Putting latter into the former doesn’t work This returns false:

{{ is_state("{{states.input_select.w_bed_light.state}}", 'on') }}

Without " it simply gives me errors.

Is there a special syntax to get the template to evaluate inner template first, then use output of that template to evaluate the whole statement?
