Disclaimer: this is sort of analysis is necessarily rough--beyond these basic estimates, talents and many other things will affect mitigation and overall tank performance in any given context.
Disclaimer 2: I didn't review your calculations or assumptions, but the approach seems reasonable.
Even based on your own conclusions, you're greatly downplaying the Warrior's mitigation advantage in your example. "Only 6.64%" is a very large difference when the Druid is only taking 33.57% of incoming damage in the first place. The Warrior (who's taking 26.93% of incoming damage) is taking 19.8% less damage than a Druid. 19.8% is a very large mitigation advantage--it amounts to a 25% increase in effective health, which is very close to the 29% higher health the Druid has in your example.

Assumptions:
- Baseline 110 warrior and druid on BFA Beta
- Build 26530
Warrior Stats:
- Baseline Physical Mitigation: 47.49%
- Dodge + Parry: 23.13%
- Block Chance: 29.46%
- Critical Block Chance: 39.60%
- Block Fraction: 30%
Effective Warrior Mitigation
If one then calculates the average damage taken (reducing the incoming DPS by the P/D chance and then adding in block and mitigation), the baseline warrior health takes 35.51% of the incoming physical damage. If we add on 100% uptime on Bolster as we already have too much rage, this becomes 31.54%. Thus, with bolster the average mitigation of a protection warrior is 68.46%.
- No Bolster: 64.49% effective mitigation
- Bolster: 68.46% effective mitigation
Another calculation worth doing is our damage reduction in our active mitigation (shield block). This gives us 100% chance to block and at 110 baseline a 69.06% chance to critically block. Thus the results are as follows:
- No Bolster: 80.07% effective mitigation
- Bolster: 82.30% effective mitigation
If we then amortize the active mitigation calculation by assuming 33% uptime (6s with 18s recharge), the average mitigation of a protection warrior is as follows:
- No Bolster: 69.69% effective mitigation
- Bolster: 73.07% effective mitigation
This does not take into consideration the change in any additional cooldowns, this is merely a base mitigation calculation.
Effective Druid Mitigation:
It's worth comparing this against a baseline druid on the beta who can maintain 100% uptime on IF (ironfur). We'll look at 100% uptime 0, 1, and 2 stacks of IF. The baseline druid has 21% dodge.
- No Ironfur: 52.42% effective mitigation
- 1 Stack IF: 60.90% effective mitigation
- 2 Stack IF: 66.43% effective mitigation
Assuming a druid can keep 100% uptime on 2 stacks of IF, the protection warrior with 100% bolster uptime (easily maintained) manages 2.03% higher mitigation without the use of shield block. With consistent shield block usage this gap increases to 6.64% higher mitigation.
