100% - 99.6839% = 0.3161%.
100% - 99.5549% = 0.4451%.
Meaning: When a Black physician is in attendance, only 0.3161% die.
And when a White physician is in attendance, 0.4451% die.
0.4451% divided by 0.3161% = approx. 1.41.
Meaning: The death rate with a White physician is about 41% higher.

That's not how it works. To compare the death rates, you would take the difference between the two rates and divide that by the rate against which you are comparing the other one.

For example, in simpler terms: a 60% death rate (group A) vs a 40% death rate (group B). The difference is 20. 20 divided by 60 = .08. So the death rate for group A is 33% higher than that for group B.

With these black babies, the difference is .00129409: 99.4451 - 99.3161 = 0.129. Then 0.129 divided by 99.3161 = 0.00129888. In percentage terms, that's 0.1% higher. NOT 1.41% higher.

correction: 20 divided 60 = 0.333333 not .08. That was a ypto.

NOT 1.41% higher.

A quibble, but that should be "41%" higher. Now, to the "meat" of your reasoning:

If you administer a procedure (operation, vaccination, pill, or what-have-you) to literally millions of people, and then subsequently notice that, say, 100 people died when the procedure was administered by a Black, but that 141 people died when administered by a White, then the race of the medical personnel is clearly a MAJOR factor. (This assumes that a multi-variant analysis was made and other possible variables - like the fact that Black physicians might tend to prefer to work in high-income neighborhoods, while White physicians might actually seek out ghettos, etc.)

Don't wish to get into an argument with you; just pointing out that my math and my logic are correct.

Dividing the difference in mortality rate by the overall survival rate (which is nearly UNITY) is mathematically possible, but yields a meaningless result.

Would like to know what the actual absolute numbers were.
